7.7.8 Custom Device

The SmartLogger can connect to third-party devices supporting the Modbus-RTU protocol,
such as the box-type transformer and EMI. Since the protocol specifications vary depending
on vendors, you need to obtain a protocol specifications file in .cfg format from Huawei and
import the file into the SmartLogger for successfully connecting to a third-party device.

Description
 If PV module compensation voltage direction is set
to PV– positive offset, this parameter specifies the
positive voltage between PV– and the ground.
 If PV module compensation voltage direction is set
to PV+ positive offset, this parameter specifies the
negative voltage between PV+ and the ground.
NOTE
If Compensation offset voltage i set to 500 V, the PID module
provides the maximum output to enhance the voltage
compensation effect. The output voltage amplitude of the PID
module is automatically capped to ensure the safety of a PV
power plant. The output voltage amplitude is also related to the
maximum system DC-to-ground withstand voltage and maximum
output voltage.
You can select Clear Data to clear active alarms and
historical alarms for the PID module.
